Trace the complete shipping rate calculation chain: carrier classes → plugins on collectRates() → ShippingRateModifier pool → totals collectors → fieldset copy mappings. Use this to understand how shipping prices are calculated, modified, and propagated during checkout, reorder, or order edit.
AI agents call magento_trace_shipping_chain to retrieve information from Magector without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool traces and analyzes the shipping rate calculation chain for diagnostic/understanding purposes. It reads and maps code structure (carrier classes, plugins, collectors, fieldset mappings) without modifying any data or triggering financial transactions. It is purely an analytical/read operation on the codebase.

Attacks that exploit this kind of access
Trace the complete shipping rate calculation chain: carrier classes → plugins on collectRates() → ShippingRateModifier pool → totals collectors → fieldset copy mappings. Use this to understand how shipping prices are calculated, modified, and propagated during checkout, reorder, or order edit. It is categorised as a Read tool in the Magector MCP Server, which means it retrieves data without modifying state.
Register the Magector MCP server in PolicyLayer and add a rule for magento_trace_shipping_chain: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Magector. Nothing to install.
magento_trace_shipping_chain is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the magento_trace_shipping_chain rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for magento_trace_shipping_chain. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
magento_trace_shipping_chain is provided by the Magector MCP server (magector). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
